2. Second question is, I put two pod directly under controlplane node by creating yaml file with kind: Pod. But when I used kubectl drain controlplane I have to use --force and after it, I am not able to see those pod in other nodes.
Matthew Robinson:
If you want Kubernetes to manage the restarting (including migration to other nodes) you will have to create a deployment or daemonset. Creating just a Pod doesn’t give Kubernetes any information about what to do if the Pod disappears.

Got it thanks, I have a. followup question. can we ask kubelet to manage static pod that has been created by us?
Let’s assume I don’t to create a deployment n all, I want to keep some pods static

I want the same behaviour like how kubelet not draining controlplane pods, I want kubelet to not to drain my static pod, if it is doing it so it should start them again as well
Matthew Robinson:
kubelet looks for YAML configuration in a specific directory on each node for the static pods. You can create your own static pods but it is unusual to need to do this. If you want a Pod to run on a specific node there are other ways to achieve this using the API server. Have a look at https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/

It is clear to me now

Hi @jitender chand the purpose of static pod is not to run your application loads. fyr:
